The bomb was found by two state troopers who had fanned out to search the area after a first bomb exploded on West 23rd Street. The photo shows a pressure cooker with a mobile phone attached to it. Loose wires are sticking out of the device, which is partially wrapped in a trash can liner and held together with what looks like duct tape.

The first bomb injured 29 people in New York. Both bombs consisted of a pressure cooker, an old-school flip phone, Christmas lights, and "small bearings or metal BBs," designed to inflict maximum damage and casualties.
